VSE: Add operators to add and remove fades

Fades add:
Adds or updates a fade animation for either visual or audio strips.
Fade options:
- In, Out, In and Out create a fade animation of the given duration from
the start of the sequence, to the end of the sequence, or on boths sides
- From playhead: the fade animation goes from the start of sequences under the playhead to the playhead
- To playhead: the fade animation goes from the playhead to the end of sequences under the playhead
By default, the duration of the fade is 1 second.

Fades clear:
Removes fade animation from selected sequences.
Removes opacity or volume animation on selected sequences and resets the
property to a value of 1.0. Works on all types of sequences.

BLF: make library glyph cache handling thread-safe

Functions that utilize glyph cache should lock and unlock cache by
calling `blf_glyph_cache_acquire()` and `blf_glyph_cache_release()`.
Function `blf_glyph_cache_acquire()` will create glyph cache, if it doesn't exist.
Locking mutex is global and shared by all fonts.

VSE: prefetching

When enabled prefetching(preview panel>view settings), a pernament running job
is created, that will render frames in the background until the cache is full.
If the cache is not filled fast enough, prefetch job suspends itself
at the last moment and will wait until it has chance to "catch up".
Effectively this will decouple rendering to separate thread, so rendering
itself is a bit faster.
Cache recycling behavior will be changed to "free furthest frame to the left
of playhead if possible, otherwise rightmost frame".

Fix (unreported) 'smooth vertex colors' operator not respecting vertex
paint mask selection

followup to rBr27bbe7cbd9b, might as well make this consistent across
all the color operations [with the exception of 'Dirty Vertex Colors'
which is python]

Fix Particles: Keyed Physics crash when clicking on a particle slot
without a valid target

rB95b9680597f5 introduced code that would skip creation of GPUVertBuf
for ParticlePointCache if the keyed physics would not have a valid
target. Missing vertex buffer would lead to assert/crash.

This code is now removed (dont see a reason why this was done? afaict
2.79 also just displayed the particles without physics in this case and
this seems to be working just fine in 2.8 as well)
